PROCESS OF ORNAMENTING GLASS SURFACES.

fiIRECIZ-ICATIOIT forming part of Letters Patent No. 334,472, dated January 19, 18216.

Application filed September 28, 1885. Serial No. 178,319. (Specimens) To aZZ whom it may concern:

Be it known that I, J OHN S. RoBERTs, of the city of Rochester, in the county of Monroe and State of New York, have invented a certain new and Improved Process of Ornamenting Glass Surfaces; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this application, in

IO which- Figure 1 is a perspective view of the tool to be used; Fig. '2, a side view of the same, and

Fig. 3 a plan view of the sheet of glass as opsprinkling or sifting finely-pulverizedtfitlll;

stgpe or similar material over the impress, which, by adhering thereto, produces the de sign, all as hereinafter described.

In carrying out my invention I employ an instrument similar to that shown in Figs. 1 and2, in which a is a rubber roller, on the surface of which is formed any design it is desired to produce on the glass.

1) is a feedingroller, which rolls in contact with the rubber roller and transfers the varnish thereto.

0 is a frame to which the parts are attached, and d is a handle by which the instrument is 0 operated.

In use the large roller b is rolled over aslab with varnish spread thereon, and it takes up the varnish and transmits it to the rubber roller. As the rubber roller is rolled over the surface of the glass itproduces theimpression 5 thereon in varnish. After this is done, finelypulverized soapstone or some equivalent material is sprinkled over the impression, and, adhering to the varnish, it produces the appearance gf grounpl or sand-blasted g afirilltw him being very perfect. *Bymhenseof this invention much labor, cost, and time are saved, and it is of especial value in those cases where but little wear or exposure comes on the glass, and in other cases where the long endurance of the design is not a matter of consequence.

It is applicable in many places where grind iing and sand-blasting cannot be conveniently one.

A similar effect might be produced by using a print instead of a roller; butit would not be so effective, as the impression would have to be put on in sections, and in some places it could not be used.

Having described my inventionnvhat I claim as new, and desire to secure by Letters Patent, is-

The process herein described of producing imitations of ground and sand-blast designs on glass, which consists in first passing a rubber roller provided with the design and coated with varnish over the glass, and'then sprinkling or sifting pulverized soapstone or similar material over the impression, as set forth. In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

JOHN S. ROBERTS.
